Description

Windows 10 Update 1803 (Spring Creators) caused some versions of MicroStation CONNECT Edition to stop working. This update impacted MicroStation installation on operating systems that are non-English such as German, Danish, Spanish and Italian. Bentley recommended avoiding this update. We worked with Microsoft to resolve this problem.

Solution

[24 July 2018]

Microsoft issued fix KB4340917 which is available via Windows Update or as a download for use by system administrators.

The issue fixed that related to Bentley is:

"Improves the ability of the Universal CRT Ctype family of functions to handle EOF as valid input." 

Users can do the following (subject to having appropriate permissions and, where appropriate, consultation with IT support):


Background (prior to availability of KB4340917 - for reference)

Bentley identified that a new Windows 10 Update (version 1803) release in April 2018 causes MicroStation to hang at startup and makes MicroStation unusable. This issue also impacts other CONNECT Edition vertical applications such as Open Roads Designer and AECOsim Building Designer.

Preventing

On Friday June 8th, Microsoft has started to block offering up Windows 1803 Update to our customers as an automatic update (until the resolution is properly resolved).

If the following registry key is found on a Win10 machine, Microsoft will not offer up Windows 1803 as an automatic update.

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Bentley

However, it will not block a user / admin who “checks for updates” from updating if they choose.
